ALBERT H. ELLIS, OF NEW YORK, N. Y., ASSIGNOR T0 WYCKOFF, SEAMANS & BENEDICT, OF ILION, NEW YORK, A CORPORATION OF NEW YORK.

eeaaoe.

To all whom it may concern;

Be it known that I,.ALBERT H. ELLIS, a citizen of the United States, and resident of the borough of Manhattan, in the city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Adding-lvlachines, &c., of which the following is a specification.

This .invention relates to adding ma chines, and its specific or imnrediate'object is to provide a simple adding mechanism which may be attached to an ordinary typewriter without"difficulty, and which in its operation entails no more work'upon the part of the operator thanis required in the ordinary process of writing. If desired, the invention as a whole or in part may be embodied in combined listing and adding machines, which correspond to ordinary typewriters with the exception that the let- 'ter types and keys are omitted and the adding mechanism is connected to figure keys only, whereby the respective amounts given upon bank checks may be written in list form and automatically added. Or if desired, many of the broad and specific features of the invention may be embodied in mere adding machines, where no types are used. Hence my invention is adapted for either a. combined typewriting and adding machine, or a combined listing and adding machine, or merelyan adding machine. In seeking to attain the specific objects of my invention, I have provided electric connections between the writing mechanism and the adding mechanism, but many features of construction will also be found useful in cases where the writing mechanism is mechanically connected to the adding mechanism. Moreover in pursuing said object I have devisedmany contrivances and combinations, mechanical as well as electrical, which will be found useful in machines whose construction varies from mine in in which my invention is applied to a type- ADDING -MACHINE, 65c.

Specification of Letters me p e t a Jung 2 191 1, Application filed November 1, 1899. Serial No. 735,449.

writing machine, it is immaterial in What manner the types are connected to the keys. Typewriting machines also usually have some part which moves step-by-step as the several keys are actuated in order to cause the types to strike the paper one after an other a suitable distance apart. In some typcwriting machines a paper carriage has this step-by-step movement and in others, asin most book typewriters, the paper is stationary and the type action travels over the paper. Whatever part of the machine it. is that has this step-by-step motion, I shall call the carriage. In the present instance I have shown my invention applied to a Remington typewriter in which the types are :mountedon pivoted type bars and in which the paper carriage is movable stepby-step.

The adding" attachment may be, and preferably is, entirely disconnected mechanically from the writing machine, but since it operates electrically, it is connected with the machine byelectric conductors, which may be flexible or rigid as desirable, The only apparatus necessary for direct attachment to the typewriter, is such as isrequired for completing the electric circuits, and this is extremely simple' In making out bills', waybills, manifests, statements, or records of any character containing columns of figures to be added, when a numeral-is printed in either the units, tens, hundreds or other column, the said numeral. will be automatically added as units, tens, hundreds, etc., according to the column in which the numeral is printed, so that the total will show upon the face of the adding machine, and may be copied therefrom at the foot of the column.

In carrying out my invention I prefer to use the ordinary figure keys-of the typewriter keyboard, and to provide for print-- ing with these keyson all portions of a' line or 'page, except the column or columns to be added, without aifecting the adding mechanism; but as soon as the paper is struck by. the figure types in a figure column, the adding mechanism operatesj For this purpose two sets of circuit controllers on the typewriter are used; that is to say, each circuit connecting the typewriter with the adding mechanism contains two circuit controllers in series with each other. One set. of circuit controllers is controlled by I of the apparatus and circuits forming a part of or directly connected with a typewriting machine, in accordance with my invention. Fig. 2 is a similar representation ofthe adding mechanism, and is to be read in connection with Fig. 1. Fig. 3 is a front elevation of the adding machine, the casing being in section. Fig. 4t is an end elevation of the same with parts .broken away. Fig. 5 is a front elevation of the adding machine on a reduced scale. Fig. 6 is a sectionthrough a portion of the main shaft of the adding machine and its countershaft. Fig. is a front elevation of the'countershaft of the adding machine and its connections. Fig. 8 is a plan of the stop bars. Fig. 9 is an end elevation of the fragment of carriage mechanism and the column gage shown at Fig.1. Fig. 10 is a side View of a typewriter key, showing a circuit controller connected thereto. Fig. 11 is a diagrammatic representation of 'a modification of my invention, whereby a plurality of columns may be added on separate adding heads; and, Fig. 12 is a longitudinal vertical section of a typewrit ing machine provided with electrical devices in accordance with my invention.

Referring first to Figs. 1, 9, 10 and 12, illustrating the apparatus connected directly with the typewriter, the figure keys a, from 1 to 9 inclusive, each operates circuitcontroller consisting of contact plates (1 and of. The plates a are electrically connected in series with one another in the circuit l. The contact plates a are the respective terminals of nine wires numbered from 9 to 17 inclusive, and extending to the adding wheel mechanism through a flexible cable or otherwise Fixed to the paper carriage frame A of the typewriter are a block b and a clamping plate 6 holding between them a series of metallic pins 72?, which stand vertically and with their lower ends exposed and on a level. These pins are the terminals of a series of wires 2 to 8 inclusive, also extending to the adding wheel mechanism through a flexible cable or otherwise.

0 indicates a guiding rail or track which is secured to the typewriter frame, as by arms A secured by screws A to front corner-posts A) of the framework it" of the typewriter, adjacent to the scale A, in front sees-e2 of which index A moves. Upon this rail 0 is a slide 0 provided with a set screw c by which its position on the rail may be iixed, and carrying a contact linger 0 adapted to make contact with the lower ends of the pins 6 when in the traverse of the pa per-carriage they are carried over the linger; the slide also is provided with a short section of scale 0 having the same divisions as the scale in front of which the index plays, and having as many divisions as there are pins 7). The slide 0 may be set at any position in front of the scale of the machine, and its position, obviously, will determine at what location .in the line of writing the circuits ofthe series 2 to 8 The device 0 with its appurtenances may therefore be termed an adding-column gage Thefingerc is the tcrn'iinal of wire 1, which, as before stated, leads to each of the contact plates (d beneath the keys.

As usual, the carriage is provided with a letter-spacing rack, A, with which engage cscapement dogs A and A which rock upon an axis A and are provided with a forwardly extending operating arm A, tron'i which is suspended, by rods A a universalbar A, arranged beneath and transversely of key levers A. To each key lever connected, by a rod A, a type-bar A, the typebars being radially arranged about a common printing center, and a platen A being mounted upon the carriage over the common printing center. Such type-bars as are counected to the keys a bear figure types. and

which i s provided with an opening 0 through which the totals may be seen. Immediately behind this opening is a shaft 7', upon which are mounted adding disks or wheels o, bearing upon their peripheries the figures from zero to 9. The hub of each disk carries a pinion and a. notched wheel f, the latter being used to turn the adding disk when the next disk to the right has completed a rotation. For this purpose each disk is provided with a tens-carrying pin f to engage with a tens-carrying star wheel f on a counter-shaft f there being one star wheel for each disk. The pin strikes an arm of the star wheel and forces it against will be closed by the finger c;

the other type-baisbear letter and chariuaer is contained in the casing F, the face of eeeeoa one of the projections of the notched wheel f, causing the corresponding disk to move one point forward, thereby adding ten units; tens or hundreds, etc., as the case may be.

In place of the pin 7' a pawl f pivoted at fa to the disk, and lightly spring-pressed against a stop f" thereon, may be used, so that in case a star wheel should be rotated by a notched wheel at a time when the parts are in the position indicated at Fig. ,4, the succeeding tooth of the star wheel will lift the pawl and slip by it, without imparting movement to the disk upon which the pawl is pivoted. 1 The fixed pin 7 answers for the second and third wheels from the left-hand end at Fig. 3, since the star wheels associated therewith are never driven by the two lefthand notched wheels, as the latter are unprovided with independent actuating mechanism.

The counter-shaft is suspended from arms f, pivoted upon an axis said arms projecting beyond the axis and carrying a stop plate f normally standing adjacent to the peripheries of the row of disks. Each disk is also provided with a peripheral pin or tappet 7. The counter-shaft is adapted to be swung backward by a rod f to carry the star wheels out of the range of movement of the pins f. lhe rod f passes through the front of the case and is there fitted with a knob f and a catch f, by which an operator may at will throw 'the star wheels into and out of operative position. -\"Vhen the star wheels are thrust backward, the plate f swings forward into the path of movement of tappets f and while the parts are in this position the crank f on the disk shaft may be rotated. and

.all of the disks turned together, until the tappets f are all stopped against the plate 7, in which position all of the disks show zero through the opening c. By releasing knob f the stop plate 7 is removed. and the star wheels swing forward again under the action of spring f until collar P on rod f abuts against a fixed part of the casing, when the device is in position to again count from Zero upward.

The disks are spaced along the shaft f by means of friction Washers f. which are splined to the shaft. A compression spring I P", hearing at one end against a collar 7 secured to the shaft, and at the other end against one of said washers, produces sutficient friction between the washers and the disks to insure the latter being rotated by the shaft at the operation of crank f. An enlarged friction disk or brake f is also splined to the shaft by means of a pin f and bears against the inner side wall of the casing at f, to prevent accidental rotation of the shaft.

Corresponding to the series of adding wheels is a. series of vertically arranged.

rack-bars or drivers It adapted to engage with the pinions f of the respective adding wheels, but normally disengaged therefrom. Each rack bar is carried by bearings 2' attached to another bar 1', the latter being hung upon parallel links 2 ,41 pivoted to the face plate of the casing. A spring 2' swings the bars it and upward and forward, and so out of engagement with the pinions. Another spring j connects bars h and 2' together, and holds the former in'an elevated position. The upper-bearing 2' of each bar 2' is providedwvith an iron armature i, and behind the armatures stand electro-magnets 1?, t 6 etc. Vhen any one of these magnets is energized, the armature and consequently the parts i and 71. are swung downward and backward so that the rack engages the pinion on the hub of the corresponding adding wheel. .The rack bars [1, all extend upward to a point near the top of the casing, adja cent to which is a push bar or actuator 7., common to all the rack bars and pivoted to the casing at N. This actuator is adapted to be swung downward by a solenoid mag net K, and afterward returned to normal position by a spring Z1 So long as the rack bars occupy theirnormal .or disengaged position, the actuator cannot affect them, but when any one of them is thrown into ongagement with its corresponding pinion, its upper end assumes a position directly under the actuator, and if the latter then operates against it, the rack bar is thrust; downward until it is stopped, during which movement it rotates its, corresponding adding disk. Upon the circuit which controls the magnet 25 being broken, the spring 2' swings the driver it out. of engagement with the pinion, whereupon the spring elevates the rack to initial position.

The extent of rotation of a. given disk determines the quantity added, sothat by arranging to stop the downward movement 'of the rack bar at various points, the quantity added at each operation can be con trolled. I have provided such a stopping arrangement in the lower part of the casing of the adding machine. It consists of a series of stop bars P arranged one above the other in av suitable frame 7), wherein 'each bar free to slide independently in a longitudinal direction. Across the frontface of the gang of stop-bars, a series of vertical grooves 7) is cut immediately .beneath the ends of the drivers 71-. So long as these grooves or cutaways are unobstructed, the driver has free movement across the face of the entire series of stop-bars, but when any one of them is longitudinally displaced the grooves are closed by such displacement,

and the drivers can only travel across the face of the stop bars until they are intercepted the displaced stop bar. It will now be understood that by selecting a certain disk for rotation and a certain stop-bar for determining the extent of its rotation, any amountmay be calculated by the machine. Vith each stop bar is connected a lever pivoted at q and to this lever is attached an armature 9 in front of which arranged an electromagnet; the nine magnets are mounted upon a suitable bracket q, and are. lettered w, 10?, u etc. When any one of these magnets is energized, the cor responding lever and stop bar P are moved, the stop bars being returned to their normal positions by springs Q lldjaccnt to the opposite ends of the stop bars are two metallic plates and r suitably insulated From each other, and each having a projection 7 standing in the path of movement of the stop bars. When any stop-bar is moved by its magnet it contacts with one projection r on each of the two plates 7 and 1", and closes a circuit which traced by wires 18 and '19 leading through the solenoid K and the battery G.

In operation, the slide or column gage c is adjusted along the rail until the third division mark on its scale (counting from the left) is opposite the point on the machine scale where the decimal point separating the dollars and cents column occurs; alter operating the letter keys to write the first. item on the page, the cairiage is moved to the left by the operation of the usual release key or spacing key until the carriage index A points to that division on the gage scale 0" which corresponds to the position of the first figure of the amount to be. written. By reason of this adjustment? of the column gage, the hundreds adding wheel (the fifth from the left at l igs. and 3) is automatically coupled to all the tigure keys at that point in the line of writing at whichnumerals in the hundreds column occur. Thus. if 230.7% is the amount. the index A will be stopped at the sixth division ot the slide scale from the left, at which point the contact finger c will be against the li tth full line pin if counting trozn the right, thereby coupling the magnet t to all thcligure keys, and simulta neously enabling any cnosen key to energize the corresponding stop-operating magnet. Then the figure keys 'l'or 2, .5 and 3 are struck in succession, then the period key. and then the figure keys for 7 and it. When key for the numeral 2 is depressed, the lever A swings dowmvardly, and by means of the connecting-rod A swings the rear typebar having the type 2 thereon up against the paper on the platen. so that the numeral 2 is imprinted upon the paper. it the same time the universal bar A is carried down by the key-lever, and the initial move- 3 ment of the spacing dogs ett'ectcd in a well -known manner through the rods i and therocker A, all as indicated by dotted lines at Fig. 12. The. key-lever also carries down the contact plate (1 so that it touches the contact plate (1. as also indicated by dotted lines whereby a circuit is closed from the key through wire 1, finger 0", wire t, magnet. t, wire 19, battery G, wires 20 and 2t, magnet 1 1 wire 10, and back to key 2 'lhe circuits of all the other magnets 1.11 and I are open at the keyboard and carriage. The energizing of magnet t throws the fiit'th rack bar or driver /L into engagement with its pinion, and the energizing of magnet 10 displaces the second stop bar. The stop bar in movin closesthe circuit of the solenoid K through wires 18 and l9, and the actuator fl' is accordingly pulled downward, forcing the rack bar down until it is arrested by the displa ed stop bar. The engagement of the rack and pinion rotates the fifth disk two points lorward, showing the figure 2 at the hundreds position, through the opening in front ol the machine. The moment the key is released. the key lever, type bar, universal bar and feeding dogs, as well asthe contact. plate (1., resume their norn'ial positions and the carriage moves a letter space, so that the circuit traced above is broken at two places by the rising of the key and the teeding of the paper carriage, whereupon the several magnets become deenergized and the springs and At? return the parts to normal position. it. the same time the mo .'e1'nent ol the paper carriage makes contact between the next pin and the finger thereby couplin the succeeding adding wheel to all the figure ktys. Next, the numcral 5 key is struck, the type 5 imprinted on the paper, and a circuit is: closed through wire 1, finger 0", wire 5, magnet t. wire battery G, wire 20, magnet in. wire l and back to key 5. This ellects an operative connection between the fourth rack bar and its adding wheel, and displaces the titthstopbar, whereupon the circuit of solenoid i is closed and the fourth disk rotated until its figure shows in the opening in 't'roiitot the casing. in the same manner each of the figures in the amount or quantity is written. in writing the second and succeeding numbers in the column. it is obvious that since the disks are constructed upon the usual plan of adding machines. they will show a total through thc'opening in the casing corresponding to the total amount written by the machine at. any given time. hen the column has been finished, the total'amount shown by th adding machine may be written under neath "the column, the hand switch or controller s having been first shifted; or it the total is written in the next column to the right. as is oitten the case, the switch .9 need lnot be operated since the position of the gage leaves the circuit in normal condit1on and prevents the-further operation of the adding mechanism.

In Fig. 1 two of the pins 19 are shown in dotted lines. On writing amounts of money, or other amojunts'which it is desired to point off with commas. or periods, such Y characters may be written in at the places where the omitted pins 'occur, without affecting any of the circuits; thus, while the amount 256.74 occupies six spaces, only five of them are figure spaces, and .only five disks of the adding mechanism would be rotated in writing it, the other space being occupied by the period, and the pin for that space being omitted or shifted. @bviously,

the position of the pins may be shifted to. bring either blank spaces or punctuation inthe term'is intended to'comprehend any carriage or connected part which is moved by the-spacing devices, orin the event of the invention being used as an adding machine ber of adding column gages 6, each contain- 'ing a set of contact pins 6 These are ad- Qjustable along' the scale to any position merely,';any suitable step-by-step moving de-.

some documents or statements often con- 'tain'a number-of similar or dissimilarcolumns'offigures which have. to be writ'ten line by line, with; the. totals in their proper places under each column. In order to do this kind 'Of'WOI'k with my invention, itvis only-necessary to provide as many different groups of pins Z1 as, there are columns, and connect-each 'group with a diflerent adding mechanism, the circuits from the key levers being common to all the adding mechanisms.

In Fig. 11 I have illustrated diagrammatically a plan forvwriting andadding more than one column of figures. vThe finger is fixed to the frame of the typewriter, andthe scale bar A, which in this instance is.

fixed to the movable carriage, carries a num-- where the columns are to be located. and secured by screws 0?. The polnter A s secured to the frame A. "The key circult controllers are'indicated by a and (L as before. ,The magnets t-and ,wof the two I adding mechanisms are shown, the magnets t in one case being connected through the cable T with one set of-pins o while the magnets t of the other adding mechanism are connected through the cable T with the other set of pins If. A cable T connects the.

circuit controlling plates a respectively with themagnets to ofboth of the adding mechanisms, and the -;magnets t, and w 'of each adding device are connected by the wires u and 1), so that any pair of them may be, put into series with each other. The battery is in the circuit 1, leading from plates a of the keycircuit controllers to the finger 0 The operation of this mechanism will be readily understood from that of the mechanism hereinbefore described, but it may be pointed out thatsince each circuit must be closed at the two points to cause the adding machine to operate, it] is evident that when one-set of pins is in engagement with the finger c only one of" the adding heads can'respond, and thatmust be the one in which the magnets t are connected wit-h the pins in operation and thereby coupled to the figure keys. When the writing ofany column is finished, its total may be read from the adding mechanism corresponding to it. It will be noted that the mechanism for controlling the rotation of the adding wheels is disconnected from the keys, and hence no portion thereof is operated, except at that portion of the line of writing during'whichthe/column gage completes the electric circuits. At this time, by the depression of any of thefigure keys, connection is efiected be extent of their. rotation, the touch upon thefigure keys remains practically. the same after as before the adding apparatus is connected to the typewritingmachine.

keys with the adding wheels and also to ro- .tate the wheels, as well as to determine the The adding-wheels may be operated when 7 the figures in the desired column, independently of any other or further movements of the carriage, so that in the operation of writing and adding a column of figures it is only necessary that the carriage shall move back and forth a distance -equal to the width of the column; while at any time, if desired,-th e. carriage may move a longer distance to enable the. printing of Words or other figures in connection with the adding column.- The-provision of a scale along which-the column gage may slide is of great importance, as it enables said gage to be instantly and accurately set to position for enabling the carriage to properly connect the adding wheels to the figure keys, so' that when the figures are printed on the paper they are also added on the corresponding adding Wheels, without liability of error or of failure of the addingwheels to act. The column gage can be set to any portion of the line of writing. At all other p'ortions of the ever the carriage is in position for writing line, whether preceding or following the column gage, words may be written, or,if

"desired, columns of. figures. may be written without affecting theadding mechanism.

)1'0N31' order. The ad'ustable blocks 0 ma l .l J

be termed column locators and the parts 5) may be termed denoininatiomtl members 5r dial determining deyices, inasmuch as there one of said parts for each denomination and each of them determines a dial to be operated.

In carrying out my improvements in their several forms it is not essential to follow the precise details oil construction herein set forth, as many changes may be made within the scope of the invention. For instance, it is imniaterialwhether the adding wheels be operated by normally open or normally closed circuits, and the claims relating thereto are tlierefore intended to cover the several features of invention, as carried out with either kind of circuit. 'llhe terms drivers and actuator employed to designate the parts it: and ii respectively, are intended as generic terms to apply to various forms of devices to accomplish the ends attained by the particular devices shown.

it will be observed that l have provided an actuator as/c, common to all of the adding wheels, which is normally out of operative.

ator being preferably connected with a suit-' able source of power, so that the wheel is not driven by power imparted to the key by the finger; that the mechanism for limiting the extent of rotation of each adding wheel is likewise preferably connected to a suitable source of power controlled by the keys; that the drivers are variably arrested by a series of stops; that each stop bar is common to all the drivers, and that the keys control means for determining by. which stop bar any moving driver shall be arrested; that each of the endwise, sliding stop bars has a series of cutav/ays, and that the bars are arranged so that.said cutaways normally register with the drivers; and that means are arranged between the series of stops pnd the actuator for causing the latter to act only after the positioning of the selected stop relatively to the driver. The axis of the star wheels is arranged eccentrically to the axis of the adding wheels. jlt will also be season seen that l have provided a series of fi keys, a step-by-step moving device that connected to a series of adding wheels, and determines which wheel shall be actuated. and suitable connections between a series of figure keys and the said wheels, whereby atter tae desired wheel has been selected by the step-bystep moving device, any oi the series of figure keys may be operated to cause said wheel to be turned to the extent represented by that key. The said stcp-bystep moving device is in this case in the "form ot a paper carriage. althoi'lgh so tar as many important features of my invention are concerned, it is not essential that a paper carriage be used, so long as a suitable moving device is provided for the purposes set forth. It will further be noted thata series of electrically operated adding wheels -is provided, each of which is adapted to be actuated by all of the figure keys; that one portion of my invention comprehends the combination of an adding wheel and electroma'gnet, means operated by the magnet for rotating the wheel, electric circuits from the magnet to all of the keys, and circuit eontrollers operated by the keys, whereby any key may be operated to cause the wheel to rotate. The solenoid magnet- K is common to all of the adding wheels, means being arranged-between said magnet and the adding Wheels for rotating the latter. A series oi magnets is provided for the series ol. drivers 72 and is included in suitable electric circuits having terminals at the figure keys, the latter being provided with suitable contacts connected together in series, whereby upon the operation of any key partial revo lution of an adding wheel is cti'ected. i lngagement is eti'ected between each rack and its pinion by electrically operated means, whereby the Pinions are enabled to be. ro tated by the racks.

Electrically operated means controlled by the f gure keys are provided for moving the stop bars. Each adding wheel is provided with its own magnet, and each stop also is provided with a magnet, said magnets bein included in electric circuits; and when said circuits are closed by the keys, a magnet from each of the said two sets of magnets is thrown into series and caused to operate. Electrically operated means are controlled by the stop bars for in'iparting movement to the actuator Z which means are automatically called into action upon the setting of a stop, the electric circuit being thereby completed that enc 'zes the solenoid magnet K. The said circuit is hence controlled by the same series of magnets that control the stop bars. The electric magnets which connect the drivers 'to the adding wheels are preferably arranged in snrics with the magnets that control the stops.

Electric circuits connect the adding wheels to the keys and also to the step-by-step moving device, each circuit containing two circuit controllers, one operated by a key and the other by the step-by-step moving device. Said circuits have terminals arranged at the step-by-step moving device, and 'a contact finger is adapted to make connection with the circuit terminals in succession, said contact device being itself adapted to .be connected with any of a series of terminals arranged at.the keys. It will also be observed that adjustable, automatically operating means are provided for rendering the adding-Wheels temporarily inoperative, so that, if desired, a space may be left between any two figures in a number written by the types, without causing ,errors in the adding operation; that a series of substantially equidistant and concentric adding "wheels are provided, together with means for enabling the carriage to couple the wheels in regular'succession to the keys at either equal .or unequal intervals in they travel of the carriage. Independent mechanism 1S provided for effecting-the rotation of each adding wheel, sald mechanism being connected electrically to the keys and to the carriage, together with means whereby any of the electric circuits may be controlled by a carriage movement, supplemented by a movement of any of the figure keys.

An adjustable coupling or connecting de vice operates automatically to couple .the wheel-actuating mechanism to the figure keys of the typewriter at one portion of the line of writing, and to uncouple all of said wheel actuating mechanism from the figure keys .at all other portions of the line,

whereby numbers may be written in a and whereby either words or figures may be. written upon each line, either preceding or. following said adding column, without af-.

column and automatically added,

fecting the adding 'wheels. The wheels can be connected or coupled only one at a time and-only in regular; order, the operation taking place when the carriage is at the selected portion of its travel and-independently of. any furthermovement thereof, thus avoiding the necessity of retracting the car- .riage a considerable distance beyond the beginning of the column in order to position the adding mechanism. A scale marked with letter space graduations is arranged in juxtapositionto-thecolumn gage, the gage and the scale-being relatively movable, whereby the gage maybe readily and accurately set,'to determine at what portion of. the line of writing the addingwheels-shall' be operated by the figure keys. It will be further noted that I have provided a'series of adding heads, each including a series of adding wheels, and electric circuits from the keys to the adding heads, whereby any key -matically operating may control any adding wheel in any adding head, a series of figure keys being combined with astep-by-step moving device, with a plurality of groups of circuit controllers respectively connected both to the adding wheels and 'to the step-bystep moving device and determining which of said adding wheels shall be in operation, andwith another set of circuit controllers controlled by the keys and common to all the adding wheels in all the groups. Any key may be operated to record the corresponding number and simultaneously operate anyiadding wheel in any adding head. Groups of circuit controllers are connected to the typewriting mechanism for determining which of the adding mechanisms shall be effective,

- An adjustable adding column gage may be provlded for either one or more of the series of adding heads; and if more than one gage is used, all of them may be made adjustable along a track so as to automatically couple its figure keys.

What I claim as new and desire to secure by Letters Patent, is

l. The combination of a series of figure keys, a series of adding wheels, an actuator associate adding head to the common to all the wheels, but normally out' of operative relation therewith, a magnet for moving said actuator and means called into action at the operation of any key for putting any adding wheel into operative relation with the actuator, and also for causing said actuator to be movedby said 11' agnet.

2. The combination of a series pf figure keys, a series of adding wheels, a driver associated with each adding wheel but normally disconnected therefrom, 'a magnet for each driver and means for enabling any of the keys to energize any of said magnets so as to connect its associated driver with its asso ciated adding wheel.

3. The combination of a series of figure keys, a series of adding wheels, a driver associated with each addingwheel but-normally disconnected therefrom, and automatically operating means, including a'system of magnets under the control of-all of said keys, for connecting the drivers, one after another with their associated adding wheels.

4. The combination of a series of figure keys, a series of adding ,wheels, ,a driver associatedwith each adding wheel but normally disconnected, therefrom, means for enabling any of the keys to connect any of the drivers with its associated adding wheel, and auto-- eans connected with a suitable independen s'eturce of power and J with the figure keys,atitd put into action by the same stroke of the 'rey that connects the selected driver with its associated addingwheel, for causing the driver to rotate the adding wheel.
